Abstract
A polymeric complex composition comprising a reaction complex formed by the interaction of a polycarbophil component with alginic acid or a salt thereof, said interaction being performed in the presence of a divalent cation and in the presence of an active agent selected from the group consisting of medicinal agents and cosmetic agents. Also disclosed is a polymeric delivery system which is formed by a polycarbophil type composition with an active agent, optionally in the presence of water and/or other cosolvent. There is also described a method of controlled release treatment comprising the steps of providing such a polymeric complex and an effective amount of an active agent selected from the group consisting of medicinal agents and cosmetic agents contained within said complex, and contacting an area of skin or mucous membrane to be treated with said composition for a sufficient period of time to allow a therapeutically effective amount of said active agent to be released from the complex. A composition and method for the treatment of xerostomia is also disclosed, comprising polycarbophil in the form of an article having a shape suitable for insertion into the mouth.
